hibernate中使用序列生成主键

xml文件：

<id name="id" type="java.lang.Long">
              <column name="id" length="19">
                <comment></comment>
              </column>
              <generator class="sequence">
                  <param name="sequence">SEQ_JbpmTaskInherit_SEQUENCE</param>
              </generator>
   </id>

创建序列：

create sequence SEQ_JbpmTaskInherit_SEQUENCE

start with 1

increment by 1

nocycle

nocache;
